Give me some tips for testing Email client mobile application
I am not familiar with e-mail but I need to test Email client for mobile platform. I suppose that there are some test engineers which can help me to define tricky use cases and well-known problems which could occur. And which articles and standards do I need to learn for better understanding?
A partial answer: email rendering is very important. Many emails, like newsletters, marketing materials, etc put a lot of effort to make their emails beautiful. Having the HTML render properly on a mobile client takes effort.
One type of test is the acid test: http://www.email-standards.org/acid-test/ You could also do side-by-side comparisons for many marketing emails, from well known email providers like mailchimp, etc...
